You live in a world full of anthropomorphic furry creatures similar to those you've seen in stuff like "Zootopia", Disney's animated "Robin Hood" and etc. However, they exist side by side with regular humans. You can be a furry or a human. It doesn't matter. However, you just moved into a new apartment one day. You take a nap on your bed after you finished unpacking, and you wake up to find a 4 foot tall mouse girl sitting on your chest. What does she want? You, of course. She says that she's your new roommate and girlfriend. You decide the rest.
